Purpose:

To determine the prevalence of myopia and hyperopia and related factors in underserved rural areas in Iran

Methods:

In this cross-sectional study, two rural regions were randomly selected in the north and south of the country through multi-stage cluster sampling. After selecting samples, all participants had non-cycloplegic refraction and measurement of uncorrected and corrected visual acuity. Cycloplegic refraction was performed for those 20 years of age or younger

Results:

3314 of the 3851 invitees participated in the study and 3271 participants were examined. The overall prevalence of myopia and hyperopia in this study was 23% (95%CI: 19.6 -26.4) and 21.59% (95% CI: 17.92 -25.26), respectively. In those ≤20 years of age, the prevalence of myopia and hyperopia based on cycloplegic refraction was 5.69% (95% CI: 4.42-6.96) and 3.25% (95% CI: 1.49-5.02), respectively. In over 20-year-olds, these values were 29.47% (95% CI: 26.26-32.68) and 28.44% (95% CI: 24.40-32.49), respectively. Multiple logistic regression models indicted that myopia prevalence significantly correlated with age, education level, cataracts, and region of residence, and hyperopia prevalence correlated with age and region of residence

Conclusion:

In our study, the prevalence of hyperopia and myopia was lower compared to other studies in urban areas of Iran, but overall, hyperopia has a high prevalence in our study and other Iranian studies. The prevalence of refractive errors significantly differs between northern and southern rural regions of Iran
